" 'VIPERFORATING ATTACHMENT.

Application filed. June 6, 1921. Serial No. 475,302.

To all. whom it may concern:

Be it known that LALBERT E. RIPLEY, a citizen ofthe United States ofAmerica, and a resident of Bay City, in the county of Bay and State ofMichigan,have invented cerf tain new and useful ImprovementsinPerforating Attachments, of which the following is a specification. y

This invention relates to perforators for perforating paper and thelike, and particularly to perforators such as used in printing shopswhere a large amount of this perforating work is required to be done. I

,One object of the invention is to design a. very simple, durable andeconomical perforating attachment which can he quickly and easilyattached to a printing press, but which is particularly designed to beattached to the commercially named Kelly press.

Anotherobject of the invention is to design an adjustable perforatingattachment whichcan be easilyadjusted to suit different weights ofpapers, and which will form a neat and clean perforation. a

With the above and other objects in view,

the present inventionconsists in the combi-' illustrating tachment in yand is provided with ,companying drawings,

nation and arrangement of parts, hereinafter morefully described,illustrated in the acand particularly pointed out in the appendedclaims, it being understood that changes may be made in the form, size,proportion and minor details of construction. without departing from thespirit, or sacrificing any of the advantages of the invention. I

In the drawings:

Fig. 1 is a fragmentary view of the rear end of a commercially namedKelly press my improved perforating atplace thereon.

Fig. 2 is a crosssectional view of one of the perforating heads.

Fig. 3 is an enlarged front view of one of the perforators and groovedrollers, and Fig. 4 is a side view thereof.

Referring now particularly to the drawing in which I have shown thepreferred embodiment of my invention. The frame of the press I haveindicated by the numeral 1, this can be of any suitable construction,standards or uprights 2 rigidly secured to the said frame, atransversely disposed bar 3 being detachably secured to the upper endsthereof. A gear casin i is secured to the side of the press, and 1sadapted to house a train of gears tain parts can be readilydeta'ched,

dle the stock not shown) for driving the transverse shaft 5 which isjournaledin the hub 6 rigid on the frame, rearwardly extending arms 7being formed integral with this hub, and a similar transverse shaft 8 isrevolubly journaled in the free ends of these arms.

A series of rollers 9 are securely mounted on this transverse shaft 5 inspaced relarear of the machine over these rollers 9, and

is engaged by the belts 12 which carry it throughas clearly shown inFig. 1 of the drawing, the stock being indicated by the numeral 14 andis printed before .it is engaged by the belts 12. a

Incertain instances it is necessary that this stock be perforated inorder that oerfor instance the well known check which is usuallyattached to a-stub; as these checks are used they are of course detachedfrom the stubs, the perforation insuring that the stock will easily tearand part on'a straight line. Iamaware that there are a number ofperforating devices in use at the present time, but these are mostlyvery expensive, being built as an individual machine, requiring theservices of an operator, to hanand feed it through the perforatingmachine. My improved attachment eliminates the service of the operatorand saves the time required for feeding it through the machine, as thestock is automatically perforated as it travels through the press, andin no way interferes wit-h the printing.

The bar 3 is secured to the uprights 2 by means of the bolts 15, anelongated slot 16 being formed therein, and a head 17 embraces the saidbar tends through this head, the upper end being threaded to receive anut 19 in the usual manner, and a shoulder 20 is formed intermediate thelength of this bolt, the lower end being bent at a right angle and onwhich is revolubly journaled the perforating wheel as shown; a bolt 18ex 21; this wheel has a comparatively wide face, and is formed with aplurality of relatively small perforating teeth 22 integral therewithwhich are adapted to pierce the stock feeding beneath it. A coiledspring 23 is interposed between the shoulder and the bottom of the head,and it will be obviou-s that by manipulating the nut 19 any desiredadjustment can be secured to suit the different weights of stock.

The head is secured to the bar 3 by means of a stud bolt Ql extendingthrough the slot and threaded into a similarly threaded opening in thehead, and lateral adjustment of the perforators can be easily made byloosening this stud.

The perforating teeth 22 travels on the groove 10, but do not engage thesides or bottom thereof, and it will be apparent that these teeth willnot be easily dulled, further, the wide face of this perforating wheelprevents the stock from crinkling and clinging to the perforating teeth,obviating the necessity of a stripper.

To prevent the bolt 18 from turning in the head a dowel 25 is securedthereto, the free end extending through a slotted opening 17 formed inthe head.

Considerable care is required in the adjusting of these perforatingrollers to suit the stock, and to insure this adjustment beingmaintained when secured, I provide a small spring member 26 which Isecure to the back of the head by means of a screw 27; this springextends upwardly and bears against the nut 19 to prevent its turning, orslots may be cut in the nut to receive the said spring if desired.

In the present instance I have shown the perforating teeth integral withthe wheel, but it will be readily understood that the teeth can beformed on a relatively thin disk and a roller with a face of suitablewidth can be secured on either side thereof, and this construction iswithin the spirit of my invention.

From the foregoing description it will be obvious that I have perfecteda simple, and efficient perforating attachment for presses, which willmake a very neat and clean perforation and which can be quickly attachedto a printing press.

What I claim is 1.- The combination with a printing press having a pairof spaced apart brackets mounted thereon, a longitudinally slotted barconnecting said brackets and detachably secured thereto, a plurality ofheads slidably and adj ustably mounted thereon, perforating meanscarried thereby and comprising relatively wide rollers having aplurality of small teeth formed thereon grooved, driven rollers beneathsaid perforating rollers and adapted to impart motion thereto and inwhich the said perforating teeth travel, and means on the heads formaintaining a pressure on the perforating rollers for positively movingthe stock over the grooved rollers.

2. The combination with a printing press having a pair of spaced apartbrackets mounted thereon, a longitudinally slotted bar connecting saidbrackets and detachably secured thereto, a plurality of individualperforating attachments slidably and adjust ably mounted thereon andcomprising wheels having a plurality of perforating teeth formedtherein, driven rollers beneath the perforating rollers, and adapted toimpart motion to said wheels, grooves formed therein and adapted toreceive the teeth of the perforating rollers, means for exerting apressure on the perforating rollers, and a plurality of means forcontinuously feeding and moving the stock to be perforated between thesaid rollers.

In testimony whereof I affix my signature.

ALBERT E. RIPLEY.
